Crankshafts are an integral part of the automotive world. No engine can run without them. Crankshafts are directly related to the overall performance of the engine and they have to be properly polished in order to be efficient.
We, Inovatec Machinery, have been in the mass finishing business for over 20 years. With the experience we’ve gained over the years, we’re determined to provide you with the best crankshaft polishing machines.
Vibratory finishers are a wonder of modern technology. They’re efficient, they’re fast and they provide spectacular polishing results. Tub vibratory finishers take things one step higher with the specialized tub for long parts.
When things come to crankshafts, they usually long and sensitive parts. So, it’s not wise to perform crankshaft polishing in a vibratory bowl. That’s where tub vibratory finishers come in.
Centrifugal machines are the latest technology in the mass finishing industry. They’re fast, they are efficient and they can do a lot of processing in a very little time. For crankshaft polishing, a centrifugal barrel finisher is a great choice.
Centrifugal barrel finishers are fundamentally different from centrifugal disc finishers. Disc finishers are designed for relatively smaller parts that are not suitable for crankshafts. But a centrifugal barrel finishing machine can do the job of polishing crankshafts within minutes.
These machines are designed for high volume industrial usage. The crankshafts are fed from one end for polishing and they come out the other end once the process is done. It’s a great tool to streamline the entire crankshaft polishing process.
Different Types of Crankshaft Finishing
As we’ve already established, no engine is useful without a crankshaft. And when things come to racing, performance is everything. Racing crankshafts usually made from titanium or aluminum. They’re lightweight and strong to withstand the power.
But one thing is common for all of them, that is crankshaft polishing. For racing crankshafts, you can’t go wrong with a tub vibratory finisher from Inovatec.
Same as any vehicle, motorcycle engines have crankshafts as well. These crankshafts are usually smaller in size but they pack as much or more power. Also, motorcycle crankshafts are lightweight parts so they are often made with aluminum.
For crankshaft polishing, we recommend that you invest in a centrifugal barrel finishing machine. Centrifugal finishers are very fast and precise. As motorcycle crankshafts are small, they will easily fit inside a barrel.
Monolithic crankshafts are the combination of the crankshaft itself and the connecting rods. These crankshafts are particularly strong and used for maximum power output.
In order to polish monolithic crankshafts, you should stick to the tub vibratory finishers. Tub finishers protect large parts like crankshafts from damaging. And if you operate on an industrial scale, you can install a horizontal polishing machine as well.
Engine parts like crankshafts are manufactured in two primary ways. One is casting and the other is forging. We’ll get the cast crankshafts later, let’s get on with the forged ones. A forged piece of metal means it’s shaped into the object with a forge. Forged parts are strong as the metal is not molten. The structure of the atoms is more even which results in more structural rigidity.
To polish forged crankshafts, you should always use a tub vibratory finisher from Inovatec. And make sure that you use the right media after consulting our support team.
The other type of crankshaft manufacturing is casting. The metal is molten and poured into a mold to form the shape of the crankshaft. It’s cost-effective and easy to produce on an industrial scale.
But cast crankshafts require polishing as well. As you’re dealing with big bulks, it’s best to go with the horizontal crankshaft polishing machine. You can use a tub vibratory finisher as well if you don’t need such a level of scaling.
Assembled crankshafts are those where the individual portions of the crankshaft are separate. They are assembled together to form the crankshaft. You can take it apart at any time you want.
As you can already guess, assembled crankshafts are subject to heavy polishing as well. You can either polish is disassembled or assembled. For disassembled polishing, invest in a centrifugal barrel finisher for faster results. And for assembled polishing, go with a tub vibratory finisher.
Crankshaft Polishing Media
Metal polishing is always great because you can visually see the difference. In order to get things right, you need to make sure that the media you are using is right. For crankshaft polish, we recommend using either the plastic polishing media for porcelain balls. If you require slight deburring, use ceramic media as well.
- A wide variety of crankshaft polishing
- All kinds of mass finishing equipment and media are available for purchase
- Expert support team to guide you in the right direction
- Best in class crankshaft polishing machines at reasonable costs
Answer: The minimum order is 1 piece. You can buy as many as you want, but we need time to manufacture them.
Answer: Polishing is mostly a non-abrasive process. And deburring requires abrasive media. That is why polishing media and deburring media are different.
Answer: If your parts have visible burrs and inconsistencies on the surface, a cycle with slightly abrasive ceramic media is recommended. Otherwise, you can stick to the plastic and porcelain media.
Answer: In general, manufacturing a crankshaft polishing machine requires 15-20 days. But if you’re in dire need of one, we can speed up the process upon request.
Answer: You need to deposit 30% of the price to confirm your order. The rest will be paid before shipping.

1. How can I polish my crankshaft?
Three primary mass finishing machines are ideal for polishing your crankshafts.
The first one is the tub vibratory tumbler. It has a robust motor that it uses to shake its polishing tub vigorously.
Figure 1 – Tub Vibratory Tumbler
When it shakes its tub, polishing media and your crankshaft will rub each others’ surfaces.
This rubbing of surfaces generates friction, which is necessary for the polishing process to be a success.
After polishing, you do not need to separate your polishing media and polished crankshafts manually.
This machine has a separating sieve, which can be adjusted to fit different sizes of polishing media.
The second primary machine that you can use is the centrifugal barrel finisher.
Figure 2 – Centrifugal Barrel Finisher
The centrifugal barrel finisher is yet another robust mass finishing machine that uses centrifugal forces to complete the polishing process.
Keep reading this article to find out how the centrifugal barrel finishing machine is an ideal machine for polishing your crankshaft.
The third mass finishing machine is the crankshaft horizontal polishing machine.
Figure 3 – Crankshaft Horizontal Finishing Machine
These machines are simply exceptional.

Unpolished crankshafts are fed into this machine horizontally. They come out from the other end, fully polished.
All the polishing action takes place inside the machine.
The crankshaft horizontal polishing machine is popular nowadays because of its efficiency and effectiveness.
Mass finishing machines are the ideal way of polishing your crankshafts.
2. What polishing media can I use to polish my crankshaft?
Now, when polishing crankshafts using mass finishing machines, you will need abrasives.
There are several polishing media that you can use to complete the polishing process.
The first one is the plastic polishing media.
Figure 4 – Plastic Polishing Media
Now, plastic is not the most rigid polishing media.
You can use it to carry out light polishing on the surface of your crankshaft.
Plastic media does not crack; neither does it chip under pressure. These features are what make it popular nowadays.
Plastic polishing media is also lighter than other polishing media.
Its lightness attributes lesser consumption of running power by the mass finishing machine.
However, plastic will not polish your crankshaft’s surface to achieve a mirror finish.
Its polish is not shiny.
The second polishing media that you can use is porcelain polishing media.
Figure 5 – Porcelain Polishing Media
Now, porcelain is more rigid compared to plastic polishing media. It contains elements of ceramic particles.
It is, however, not too aggressive as compared to ceramic or stainless steel polishing media.
These attributes make it an ideal candidate for polishing crankshafts’ surfaces.
The last polishing media that you can use is ceramic media. Now ceramic is only used under certain conditions.
Figure 6 – Ceramic Polishing Media
Check this out:
You can use ceramic media to polish your crankshaft when they need a slight deburring.
Ceramic media is highly aggressive, and it can scratch the surface of your parts if you are not cautious.
All these polishing media come in different shapes and sizes.
These dynamics are necessary for a clean and uniform polish, including the most intricate corners.
Selecting the right shape and size for the polishing process is crucial.
You’d not want to have media lodging in your crankshaft’s cavities or pockets.
These polishing media also need to get into contact with these pockets and polishing media.
They have to clean every inch of your crankshaft.
All these polishing media also polish exceptionally well when using polishing compounds.
Polishing your crankshafts by using abrasives is the most effective way of getting rid of blemishes on the surfaces of your crankshafts.
3. How can I polish my racing bike’s crankshaft?
Most racing crankshafts are made from aluminium or titanium. These metal types are light and robust.
Check this out:
When polishing racing crankshafts, the best way is to clean them using a tub vibratory tumblers.
You can decide to use either porcelain or plastic polishing media.
Remember, if your crankshaft requires light deburring, you can decide to use ceramic polishing media.
When polishing these racing crankshafts, you need to be extremely cautious.
One single mistake can result in slight damage, which renders the crankshaft useless.
A tub vibratory polishing machine does not alter the shape or dimensions of your racing crankshafts.
You cannot afford to damage your racing crankshaft.
Therefore, the best way to polish racing crankshafts is by using a tub vibratory tumbler.
4. How long does it take to polish my crankshaft?
Now, the duration it takes to complete the crankshaft polishing process depends on three primary factors.
Check this out:
The first factor is the polishing media that you decide to use.
Using ceramic media will polish faster than any other polishing media.
It is highly aggressive.
Also, using porcelain media over plastic polishing media will complete the process faster.
However, using ceramic and porcelain polishing media will require your machine to use more energy when polishing crankshafts.
Plastic polishing media is lighter than other polishing media. Synthetic media is 40% lighter than ceramic media.
The second factor is how you decide to handle your machine.
Running the process using the optimum polishing conditions, such as the polishing speed and the use of polishing compounds, matters significantly.
If you decide to use an incredibly fast polishing speed, then the final output will not be sound.
Also, the process will take too long to complete if you decide to use an incredibly slow speed.
It will, therefore, become uneconomical.
The third factor is the level of damage on the surface of your crankshaft.
Figure 7 – Dirty Crankshaft
If it requires heavy polishing, then the process will undoubtedly take longer to complete.
Your decisions significantly affect the quality and efficiency of the polish that you require on your crankshaft.
5. How does the centrifugal barrel finisher polish crankshafts?
When polishing crankshafts using a centrifugal barrel finisher, the machine uses the following technique to clean.
You’ll first have to understand that this machine uses centrifugal forces to polish.
First, the machine has four barrels affixed to a single flywheel which spins.
The flywheel and the polishing barrels spin in opposite directions, respectively, to increase effectiveness and efficiency.
Figure 8 – Centrifugal Barrel Finisher
The machine spins its polishing barrels at an incredibly fast speed. It thus generates powerful centrifugal forces.
These forces then cause immense stress on the polishing media and the target crankshaft.
This stress causes media to polish your crankshaft effectively by abrading its (crankshaft’s) surface.
You can also use polishing compounds with this machine.
You can use this machine to polish to the highest degree, and also for light deburring.
6. What is the benefit of polishing crankshafts?
